srECiFICATIoN rormingvpart of Letters Patent No. 738,687, dated september s, 190e. l Appnationneacrune,1903, serninofleogs. (Nomaden TINGER, a citizen of the United States, residing at Central City, in the County of Muhlenberg and State of Kentucky, have invented 'certain new and useful Improvements in Harrows; and Ido declare the following to be a j specification.

full, clear, fand exact description of the invention', such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, `and to the letters of reference part of this A t collar G. Each of said blocksl carries a spring-bar J, having a hook J' formed therein, adapted to engage over the inclined edge marked thereon, which form a This invention relates to new and useful imj provements in harrows, and especially in an 'apparatus in which the harrows may be thrown automatically into operation and out. of gear by suitable rotary mechanism, and' comprises means whereby the harrow may be raised or lowered to adapt the machine for 'various conditions `of ground.

`harrow. Fig. 2 is a cross-sectional view show' ing parts in elevation. Fig. 3 is a rear view.

Fig. 4' is a" longitudinal section through the apparatus, showing'parts in elevation. Fig. 5 is a detail `view of the automatic coupling device, and Fig. 6 is a top plan view of the detail shown in Fig. 5.

Reference now being had to the details of the drawings by letter, A designates the axle ofthe machine, which supports a cross-piece A', to which the tongue B is fixed. Journaled upon said axle are the driving-wheels C, one

of which has a gearedwheel D fitted to the spokes `of the wheel and 'adapted to drive mechanism for reciprocating harrows, as will presently be' "described,` Fastened to said cross-.piece A' are the beams E, (shown clearly in Fig. l of the drawings,) which beams have containing harrow-teeth F3. L

` G designates a collar, detail views of which are shown in Figs. 5 and 6, which'collar is fixed to one of the arms of the shaft F, prefcured to each end of said shaft is a frame F2 erably in the location illustrated in FigLBof t the drawings, and fixed to the shank portion of Vsaid collar, which radiates out fromuthe latter, are the blocks H, Figs. 5 and 6, which `are apertured, as at II',- one wallof eachof said apertures being inclined, as at h, and I I designate blocks, which are pivotally mounted, as at I', upon the shank portion of said h of an aperture H (shown iuFig. 5) for the purpose of locking the pivotal blocks I in a closed relation or in the position shown in Fig. 3 of the drawings.

Each of the blocks I has fixed thereto a bar K, and upon the adjacent edges of the fixed blocks I and H are concaved recesses K', adapted to receive the T-shaped eudL of the pitman L', a detail view of which is illustrated clearly in Fig. 6 of the drawings. to a pin L2, eccentrically mounted upon the face of the gear-wheel L3, the latter being iixed to rotate witha shaft M, mounted in suitable bearings upon the machine and be- Said pitxnan L' is pivoted ing in mesh with the gear D, which is fixed to rotate with a driving-wheel, Fig. l of the free ends will "engage the portions ofthe spring-hooks J and disengage the latter from the edges of the blocks I-I, `thereby allowing the blocks I to fall by gravity intoth'e position shown by dottedlines in Fig. 5 of the drawings.

The. outer ICO Qdesignates a lever,which Ais fulcrumed at Q' upon a bracket-arm'supported by the crosspiece A.

One end of said lever Q hasan eye throughwhich the rock-shaft has a reciprocal movement, and when the free end of the lever Q is depressed the arms E2, carrying the shaft F, may be raised from the ground, and when in raised position said harrows, after the blocks I are thrown into the positions shown by dotted lines in Fig. 5, will be disconnected and idle. For holding the lever Q depressed a hook Q2 is provided, under which the end of the lever Q is swung, as will be readily understood.

R designates a cross-beam having an offset or dropped, portion R', in which the tongue of the apparatus is positioned, and secured to said beam R are the rods R?, the lower ends of which have a play in the hollow boxes R3, which support the shaft R4, upon which are mounted the winged harrow-disks R5. The lower end of each rod R2 carries a pin r,which is mounted in elongated slots r in the hollow boxes R3, whereby said rods may have a movement independent of the boxes.

R6 designates hollow boxes in which the shaft R4 has bearings, and rods R7, similar to the rods R2, have slight movements independent of the boxes R6, the upper ends of the rods R7 being fastened to bracket-arms R8. (Shown in Fig. 4 of the drawings.) Springs R9 are interposed between the hollow boxes and the cross-beam and bracket-arms R8, respectively, whereby the rotary winged disks may yield slightly when the apparatus passes over uneven ground. Said' beam R is supported upon the tongue by a plate S,

and a lever S is pivoted at S2 upon the tongue and, passing over the plate S, engages underv a hook S3 to hold the plate to the tongue. If for any reason it is desired to allow the beam to be raised from the tongue in case a large obstruction is met with, said lever S may be thrown to one side and the beam allowed to be raised from the tongue. In order to permit a further vertical movement of the beam R, the arms T, whichare fastened to the beams, have hinged connection with the beams E, and sliding wedgeshaped blocks T/ are mounted upon said beams E and are connected together by a bar T2, and staples W and WV' are provided, which are mounted upon the adjacent ends of the beams E and armsl T, respectively, and a lever V is pivotally mounted -at V upon a bracketarm of the machine and has link connections V2 with the bar T2, whereby as said lever is thrown in one direction or the other the wedge-shaped blocks T may be thrown over the hinged connections between beams E and arms T or withdrawn in the position shown in full lines in Fig. l. lVhen the wedge-shaped blocks are thrown to assume the positions illustrated by dotted lines in Fig. l, they will be held from being thrown upward, and when in the position shown'by full lines the arms will be allowed to rise after the lever S has been swung' in order io clear the plate which supports the beam R.

The operation of my machine will be readily understood when considered in connection with the foregoing and the drawings, and is as follows: As the machine is driven over a field a reciprocating movement is imparted to the harrows, which are mounted upon the ends of the shaft F, said reciprocating movement being effected by the gear connections with the driving-wheel. In case it should be desired to throw the reciprocating harrows out of gear the operator causes the shaft O to be rocked by throwing the lever O', connected therewith, sidewise. This movement of the leverO will cause the lingers O3 to bear against the spring-hooks J, clearing the latter from the edges of the blocks H, and the 4blocks I will fall by gravity, and by depressing the free end of the lever Q the shaft F may be raised so that the pitman L, still supported by the rod. O, will reciprocate in the eye thereof without actuating the shaft F. When it is desired to throw the reciprocating harrows into operative relation, the free. end of the lever Q is raised and the shaft carried thereby lowered, and as the T-shaped end of the pitman comes in contact with the bars K, fixed to the blocks I, the latter will be thrown into the positions shown in Fig. 5 of the drawings, in which the hooks J' will engage over the edge of the block H and cause the shaft carrying the harrows to reciprocate.

By the provision of automatically-operated mechanism for throwing' the harrows into gear and by the other features whereby the forward part of the harrow carries the rotary disks an apparatus is produced which is adapted for use over both level and uneven fields.

While I have shown a particular form of apparatus illustrating features of my harrow, it will be understood that I may make alterations in the detailed construction of the same, if found desirable,without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new,"and desire to secure by Letters Patent, is-
